l i rangement Patented Jan. 12, 1932 III-UNITED STATES PATENT OFFICEPANY, OF SPOKANE, WASHINGTON DUST REMOVER Application filed August 20,1930. Serial No. 476,517.

My invention relates to dust removers and is an improvement over thedevice described in my co-pending patent application for dustcollectors, Serial Number386,833, and filed August 19, 1929; and isalsoan improvement over the device described in my co-pending patentapplication for air cleaner cases, Serial Number 418,222, andfiled-January 3, 1930. Certain objects'of my present invention are toprovide dust removing elements, meansfor causing an eddy current oftheair whereby the dust is more effectively removed, a novel arrangementand disposition of the dust removing elements,'and a simplified arin thestructural details as a whole. I r

"With the above and other objects in view which will appear as thedescription proce'eds, the invention consists of the novel construction,adaptation, combination and ar rangement of parts hereinafter describedI and claimed. These objects are accomplished bydevices illustrated inthe accompanying drawings; wherein: I I I Figure 1 is a view insideelevation showing my device installedon the forward portion of amo'torvehicle; Figi 2 is a view'in central vertical'section of the devicetakensubstantially on abroken ii eaeerui l; j

'Ff'g. 3 is a View inhori zontal section of the same taken on abroken'lme 3', 3 of Fig. 1;

Fig.4 is a detail view in perspective showing-the cover andits-"attached cleaner elements.

Referring to the drawings throughout which like referencenumeralsindicate like parts,-the numeral 5 designates the casing having anoutlet 6 at its rear side portion through which the cleaned air passesto the engine through the carburetor by means of a pipe 7, and an inlet8 at its forward side portion through which oil and gas vapors aresucked from the crankcase by means of a connecting pipe 9 as shown inFig. 1. Said casing is provided with a bottom portion 10 bolted orotherwise secured thereto and adapted to retain a pool of oil 11 for thepurpose of rei moving some of the dust from the air passing Roy Runyon;or SPOKANE, WASHINGTON, ASSIGNOB TO 0. n. 0. AIR CLEANER CO'M-therethrough. A plug 12 may be installed in said bottom for drawing offthe oil and the casing may be secured to a fixed part of a motor vehicleby a bracket 13.

The casing 5 is provided with a cover member 14 fitting thereinto andhaving an entry port 15 for the admission of air. Said cover isintegrally or otherwise provided with a right angled triangular metalframe designated as a whole bythe numeral 16 and having its acuteangular portion fixed to the cover at the rear side of the entry ports.When said cover is installed on the casing the triangular metal frameprojects downwardly into said casing nearly the full depth thereof withits forward side or hypotenuse l7 slanting outwardly to form arestricted passage 18 adjacent the bottom portion 10. The bottom portionof the frame is concave, as at 19, for reasons presently explained andits rear side 20 is disposed in parallel spaced relation with the rearside wall portion of the casing.

An upstanding bracket 21 may extend from the lower portion of thetriangular frame 16 to the cover 14 in order to strengthen the supportof the frame. A baffle 22 secured to said cover member at the forwardside of the entry 15 is arranged to direct the incoming air downwardlyand against the slanting side 17 of the triangular frame. Another baffleplate 23 is formed on the interior of the casing 5 at the restrictedpassage 18 and serves to direct the incoming air against the oil pool 11as will be understood.

A number of rolls 24 are disposed in spaced apart relation transverselyof the slanting side portion 17 of the triangular frame 16. Said rollsare made of wire mesh and filled with suitable absorbent material 25 andtheir depressed end portions are soldered or otherwise secured to theside edges of said slanting frame portion. At each ed e of said slantingframe portion a corresponding roll 26 is secured in place for thepurpose of intercepting air which may pass between said edges and Y theinterior wall of the casing 5.

in Fig. 2 of the drawings, said rolls are alternatively secureda-gainst'and away from said rear triangular portion so that the outgoingair may pass inside and outside of said rolls as will be understood. Apocket member 29 made of sheet metal and open at its bottom is providedon the rear interior side portion of the casing 5 and in alignment withthe outlet 6. Said pocket watches and prevents any oil from being suckedup and out ofthe casing from the oil pool 11 by the air.

In the operation of my device the suction stroke of the engine causesair to be drawn inwardly through the entry port 15, and also draws oilsaturated air through the inlet 8 from the engine crankcase which servesto lubricate the rolls 24 and 26. The incoming air is directed by thebaffle 22 against the slanting side 17 of the triangular frame andagainst said rolls. Much of the dust is removed from the air by adheringto the oil soaked absorbent material within. the' rolls as the airpasses downwardly to the restricted passage 18. Y

The velocity of the air is increased by the restricted passage 18 wherethe air is directed by the bafiie 23 against the oil pool 11. The airrebounds upwardly from the surface of the oil tothe concave bottomportion'19 of the triangular frame whereby it is caused to eddy orwhirl. around as indicated by direction arrows in Fig. 2. In thiswhirling mo tion the air repeatedly comes in contact with the oil poolcausing muchdust to be removed therefrom by adherence to the surface ofthe oil pool. Any small amount .of dust which might remain in the air isremoved there from by the rolls 27 as it passes inwardly andoutwardlytherethrough on its way to the outlet 6 and to the engine. i

It will now'be apparent that I have provided an improved means forremoving dust from the air prior to its entry throughthe carburetor intothe engine. Having thus described my invention, it being understood thatminor changes may be resorted to in its construction and arrangementwithout departing from the scope and spirit of the invention. what Iclaim and desire to secure by Letters Patent of the United States is 1.A dust remover having in combination, a casing, a detachable bottom forthe casing,

a pool of oil in said bottom, a cover member having an air entry porttherein, a triangular frame connected to the cover member'adja'cent'theair port, said framearranged to extend into the casingtoform arestricted passage therewith, screen rolls secured in transverse spacedrelation to the slanting side of said frame between said air entry-portoutlet means, and absorbent filler for all of said screen rolls.

2. A dust remover having in combination a casing, a detachable bottomfor the casing, a pool of oil in said bottom, a cover member having anair entry-port therein, a triangular frame connected at its acuteangular end to the cover member adjacent the air port and adapted toextend into the casing to form a restricted passage therewith, screenrolls secured in transverse spaced relation to the slanting side of saidframe between said entry port and restricted passage, screen rollssecured tothe side edges of said slanting triangular frame side, oilsaturated absorbent material within all of said screen rolls, air outletmeans for the casing, a plurality of screen rolls secured in spacedapart relation to the side of the triangular frame between the oil pooland the outlet means, and oil saturated filler within said rolls.

8. A dust remover having in combination acasing, a detachable bottom forthe casing, a pool of oil in said bottom, a cover member having an airentry port therein, a triangular frameconnected at its acute angularendto the cover member adjacent the air port and adapted to extend intothe casing to form a restricted passage therewith near the bottom of thecasing, screen rolls secured in transverse spaced relation to theslanting side of said frame between said air entry port and restrictedpassage, oil saturated absorbent filler for said rolls; screen rollssecured to the side edges of said slanting side and having oil saturatedabsorbent material therein, a bafiie for the. air entry ports arrangedto direct incoming air against said slanting frame side and screenrolls,'a bafile for the restricted passage adapted to direct air againstthe oil pool, a concave underside for the triangular frame adapted tocause an eddy current of the air against the oil pool, air outlet meansfor the casing, a plurality of screen rolls secured in spaced relationto the side of the triangular frame between the oil pool and theoutletmeans, oil saturated absorbent filler for said rolls, said lastmentioned rolls disposed in staggered relation against and away from thetriangular side, and an oil pocket interposed between the oil pool andthe air outlet means. 7 1
